Volker, you opened a few threads on at least two ng's, that's
crossposting. I am not a purist, but some may not like it. I used to do
this and now I've learnt the lesson!

Http, as long as I know, does not offer persistent connections. Don't
be fooled by some http1.1 features, such as keep-alive, they have
nothing to do with a persistent connection. You can use session,
and other tricks, but you have to use a scripting language
(php, for instance) to do the job.
If you want true persistent connection, don't use http.
